Tips to troubleshoot your computer-based setup

Tips to troubleshoot your computer-based setup

If you are experiencing issues with your computer-based setup, this article will help you to troubleshoot it.

The goal of every performing musician is to have a glitch-free and reliable setup for their gigs. If things start to go awry, don’t worry – we have compiled tips to help you find the culprit easily.

Let’s get started!

[1] What changed in your system?

If your setup worked very well and suddenly started to malfunction – something changed. There is no magic! as David Jameson has often said, meaning that something had to have changed, otherwise it would have just kept working. The best advice here is to try to remember exactly what you did before your setup started to glitch. (By the way, we are assuming here that the issue is not due to a new hardware malfunction) For example, you perhaps mapped a note on your keyboard to a widget and didn’t click Thru in the Widget Properties Inspector, so hitting that note doesn’t produce any sound.

One of the most frequent culprits is various automatic updates that happen in the background.

Optimization of macOS Monterey for live performance

Your operating system, firmware, drivers, third-party software or plugins may update automatically and start causing troubles in your setup. We strongly recommend that you disable these updates and update manually. Further, do not perform any updates if you are within at least two weeks of an upcoming show so that you have time to correct any possible issues caused by updates. Note that updates can impact or break plugins, drivers and other operating system functionality, it is not specifically restricted to Gig Performer.

There are even Gig Performer users that install updates very rarely, following the slogan – Don’t fix if it ain’t broken.

To help you with various automatic updates and having them under your control, we have provided Windows guidelines and macOS guidelines that will help you to configure your computers and make them the most reliable gigging platform.

Note: Some operating system upgrades/updates can cause the computer to “look” like it is a new or different computer, thereby requiring Gig Performer or your plugins to be reactivated. Click here to learn more.

[2] Try with a USB MIDI interface

There are keyboards that are not “class compliant” and so require drivers to be installed, as noted in this thread. For example, the Korg Kronos is reported to work better with a decent USB-MIDI interface connected to the Kronos MIDI ports rather than using the USB interface. As a general rule, try to avoid non-class compliant hardware.

Korg Kronos USB and MIDI Connectors

Therefore, if you experience lockups on your keyboard when using the USB port and need to restart it or your audio plugin host, try with a dedicated MIDI to USB interface and use the standard MIDI ports of your keyboard.

[3] Be familiar with known bugs for your MIDI controller

If you experience problems with your setup, it makes sense to first check if there are some known problems with your rig. For example, in this thread a community member found out that there is a known buffer issue with his keyboard, so when the USB buffer is full the keyboard simply stops sending data. As he reported here, this issue is fixed in newer makes of his keyboard.

[4] Check on what MIDI channel your keyboard sends data

It may happen that you accidentally hit a wrong button on your keyboard and you cannot hear any sound at all. In this case, you probably changed a MIDI channel on your keyboard and your plugin doesn’t respond to that channel. Note that there are plugins that respond only to channel 1 and do not responding on (say) channel 2, as reported in this thread.

The MIDI In block is useful for these situations – you can simply map all incoming messages to channel 1:

All source channels are mapped to channel 1 in Gig Performer

You can afterward save this configuration as a Gig Performer Preset for further use.

Alternatively, the MIDI Channel Constrainer plugin, bundled in Gig Performer, can be used for these situations (visit this blog to learn more).

Another example is this thread, where the MIDI controller was sending out MIDI messages on channel 12. Some plugins didn’t care and just worked but, in this case, the Keyscape plugin by default would only respond on MIDI channel 1 and at first it looked like Gig Performer was broken (“Mistrust the obvious“).

[5] Variations are skipping or songs advance two steps

From time to time, we can see similar threads in the community forums. For example, in this thread a user mapped the Next Variation and the Previous Variation in the Global MIDI options to a CC button on his keyboard, so every time he pressed the button, instead of switching to the very next variation, Gig Performer skipped one. The solution is simply clicking on the Momentary button:

Momentary button in the Global MIDI options

In this case, if you don’t click the Momentary button, then the variation will change when you press the button and it will also change again when you release the button (hence a variation will be skipped). Another examples: here, here, here, and here.

Note that you have this Momentary/latching behavior in the Setlist Options and the Widget Properties Inspector.

[6] Try with different rig and cables

To narrow down the issue, another possibility is to replace components of your setup with different ones. Here are some tips:
– try with different MIDI or USB cables,
– try with a different audio interface,
– try a different USB port on your computer (especially if you have multiple USB 3.1 or USB 2.0 ports),
– try with a different MIDI controller,
– try with the same rig, but with a different computer,
– if you use a USB hub, try connecting your keyboard directly to your computer’s USB port (NB: make sure that you use a powered USB hub).

An example is shown in this thread, where a community member tracked down the issue by replacing his keyboard with another one.

In another example a keyboard started to glitch just before the gig:

Korg Kronos Failed before the gig

[7] Plugin-related issues

Gig Performer supports VST3, VST and AU plugins (Mac only). It can happen that one format of the same plugin is better developed than the other or the manufacturer says that one format is dedicated for a specific platform (see an example here).

For example, in some AudioUnit plugins, their GUIs doesn’t display correctly, as in this example:

Wierd GUI on the Keyscape plugin, AU (AudioUnit) format

As a remedy, simply try the a different plugin format (which was a solution in the above-linked thread).

In some cases, setting the Loading type as Delayed in the Plugin Manager can solve issues with a plugin. This is a mechanism that is put in place to deal with plugins that don’t initialize themselves properly when first loaded (see an example in this community thread).

If you happen to be a Mac user with the new M1 chip and Gig Performer cannot find your plugins, please read this article.

If your plugins crash, make sure to read this article to see possible solutions.

[8] Ask in the Community

If you still have a problem that you cannot track down, please create a new thread in our Community forums. Make sure that you explain your issue thoroughly and give as many details as possible about your setup. In this thread you can learn what information is beneficial for troubleshooting an issue. You can also search the community forums to find similar issue to yours.

Issues with plugins from certain developers

Scaling Curves

Scaling curves allow you to control the shape of the output of a widget or convert an incoming note velocity to a new velocity. Various predefined curves are available and they can be tweaked as necessary. You can also just draw your own curve as well to achieve the effect you require.


MIDI File Player Plugin

You can load up to 128 MIDI song files in a single plugin instance. Switch from one song to another, mute tracks and/or change their channel numbers. Tempo can be controlled by individual songs or you can use the global tempo and tap tempo to control the BPM interactively.


Favorites and Presets

Create a sound by placing and interconnecting your desired plugins, such as a synth, some effects and perhaps a mixer. Select them all and then save the selection as a named favorite. The favorite will subsequently show up in all plugin insert menus, making it easy for you to recreate that configuration whenever you need it again. This feature is also very powerful for creating your needed sounds on your studio computer and then transferring them to your touring laptop.


Probabilistic Sound Designer

Parameters you select in an open plugin are captured into the Probabilistic Sound Designer dialog window. When you click Randomize, you're only adjusting those selected parameters. Each entry in the PSD dialog has a curve but unlike widgets where the curve controls scaling, in the PSD the curves are used to define the probability of particular values being selected. Make sure the filter cutoff never gets too slow so as to block all sound. Perhaps adjust the max range of the VCA attack parameter so that the sound doesn't have too much delay. Constrain the octave ranges of the oscillators, perhaps ensuring that 1/3rd of the time we select 8' and 2/3rds of the time we select 4'. The possibilities are endless.


More Widgets

Numerous new widgets are included in Gig Performer - a new sustain pedal, plastic knobs, drum pads and more colored sliders. Shapes can be colored with different borders and fill colors and morphed from rectangular to circular. Your creativity is now the limit to creating fabulous front panels in Gig Performer.


MIDI Message Helper

Select MIDI devices by name. Choose the MIDI message type and adjust the appropriate parameters for the specific type



Layout management

Gig Performer supports arbitrary resizing. Layout your widgets the way you want - resize the main window and the widgets will grow or shrink as necessary to maintain the same interrelationships. No matter what size screen you have, your front panels will still be neat and usable.


Undo Support

If you move your widgets around and/or resize them, or even delete them by mistake, the Undo facility will correct your mistake. Minor moves to a widget by mistake will no longer spoil your design


Plugin Channel Count

Some plugins support a large number of outputs and they depend on the traditional channel strip to control how many ports should be available.   When you only need a stereo pair, it is convenient not to have a large horizontal block. In Gig Performer, the number of available ports  is controlled by the channel count override, which can be applied to individual plugins and will be remembered when the gigfile is reloaded or if the plugin is saved as a favorite.


Input muting and output fading

Rather than a single audio length tail, Gig Performer 4 gives you the ability to control input muting and output fading separately. Input muting controls how much time it takes for audio input to be silenced when you leave the rackspace. Output fading controls how much time will be taken for audio to fade out when you leave the rackspace.


Faster Plugin Finder

Instead of searching through menus of perhaps hundreds of plugins (you know who you are!), the Quick Plugin Finder makes it easy to find the plugin you need by simply typing partial strings. For example, as shown here, to find the Modartt Pianoteq 7 plugins, it's enough to type pia mod 7 (in any order, by the way)  to restrict the list of available plugins to those matching your query. The Quick Plugin Finder also knows about manufacturers, presets and favorites.



Touch Friendly Input

Any entry field can be changed by either dragging your mouse (or finger) up or down, or by using the large popup touchpad where you can just tap on the squares to enter a value. The large popup keypad also does validation so you can't enter an invalid value. You can also just tap the BPM field to pop up a larger view where you can quickly change tempo, tranpose, trigger Tap Tempo and enable Ableton Link, the last allowing you to synchronize Gig Performer with any other application that also supports Ableton Link.


New Tuner Display

The tuner view makes it easy for guitarists to quickly check and adjust their tuning. You can toggle into the tuner view from any other view and toggle right back as soon as you're done. All output will be silenced automatically while you're in tuning mode. You can adjust the concert reference pitch from its default of 440 Hz to suit your own needs. The tuner view fills the entire screen so you can easily see it from a distance.
